SPECIFICATION forming part of Letters Patent No. 286,634, dated October 16, 188.3.

Application filed April 7, 1893. (No model.)

To @ZZ whom #may concern,.-

Be it known that I, JOHN PHILLIrs, a citizen of the United States of America, residing at Boone, in the county of Boone and State of Iowa, have invented a new and useful Improvement in Snow-Flows, of which the following is a specifnfcation, to wit:

This invention relates to ,an improvement Y in snow-plows for railroads; and it consists in a truck. carrying a steam-boiler, one or more steam-cylinders adapted to drive a cutting-V wheel, and curved wings set at an incline to throw off the loosened snow, substantially as will be hereinafter more fully described.

In order to enable others skilled in the art to which my invention appertains to make and use the same, I will now proceed to describe its construction and operation, referring to the accompanying drawings, in which Figure l is a planview of the machine; Fig. 2, a side elevation; Fig. 3, a front elevation,

l and Fig. 4 a cross-section through one end of the cutting-wheel. Fig. 5is a section through a a?, Fig. 4:.

A represents a frame or platform mounted upon suitable wheels, A', and Vprovided with a tender, A".

Upon the platform or frame A is mounted a steam-boiler, B, connected to suitable steamcylinders, B', uponthe forward corners of the frame, and provided with piston-rods b, as shown.

Upon the forward end of the platform A, in. such a position as'tonearly touch the track, and reaching entirely across the machine, is a cutting-wheel, C, formed with transverse grooves c c, which are very shallow near vthe center of the wheel, but incline toward each end, so aste throw the snow outward. These grooves or valleys are separated by cutting ridges or knives c', as seen in Figs. 3 and fi. Each end of d the cutting-wheel is furnished with a wrist-pin, c2, connected by a pitman, C', with the piston-rod?) of the adjacentsteamcylinder.

The frame A is arched in front, as seen at c, and the sides of this arch are beveled or turned outward to form cutting knives or edges a', which cut the bank of snow upon each side of the wheel C. Above this arch a is located a small cab, E, for the accommodation of the operator, provided with a head-light, E.

, G represents curved wings, meeting in a point over the center of the cutting-wheel C, and inclined outward and upward toward the rear end of the plow,to aid in carryingoif the snow.

In operation the device is intended to be placed upon the track ahead of an ordinary locomotive, which pushes the plow ahead of it. W'hen snow is found upon the track, the operator in the cab E allows steam to enter the cylinder B', thereby rapidly revolving the cutter-wheel C in a direction the reverse of the motion of the truck-wheels A. This rapidlyrevolving cutter loosens up the snow and lifts and throws it upon the curved wings G, from which it is carried off at the sides and rear.

Having thus fullyT described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In asnow-plow, atransverse cutter-wheel formed with grooves inclined from the center toward each end and separated by cuttingridges, substantially as described and shown.

2. In a snow-plow, the truck A, boiler B, steam-cylinders B', having pistons b, and the cab E, supported over the forward end of the machine, in combination with the revolving cutter C, formed as herein shown and described, and connected by a pitman with the piston b, and the wings G, all constructed and arranged to operate substantially as and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.

JOHN PHILLIPS.
